Directions

1. Whisk the egg yolks and sugar together in a medium bowl until light and creamy.
   
2. In a saucepan over medium-high heat, combine the cream, milk, nutmeg, cinnamon and salt. Stir often until mixture reaches a bare simmer.
   
3. Add a big spoonful of the hot milk to the egg mixture, whisking vigorously. Repeat, adding a big spoonful at a time, to temper the eggs.
   
4. Once most of the hot milk has been added to the eggs, pour the mixture back into the saucepan on the stove. Whisk constantly for just a few minutes, until the mixture is just slightly thickened (or until it reaches about 160 degrees F on a thermometer). It will thicken more as it cools.
   
5. Remove from heat and stir in the vanilla, and brandy, if using. Pour the eggnog through a fine mesh strainer into a pitcher. Refrigerate until chilled.
   
6. It will thicken as it cools. If you want a thinner, completely smooth consistency, you can add the entire mixture to a blender with 1 or 2 tablespoons of milk and blend until smooth.
   
7. Serve with a sprinkle of cinnamon or nutmeg, and fresh whipped cream, if desired. Store homemade eggnog in the fridge for up to one week.
